You must either add a leading zero so that Ansible's YAML parser knows it is an octal number like or or quote it like '' or '' so Ansible receives a string and can do its own conversion from string into number. Giving Ansible a number without following one of these rules will end up with a decimal number which will have unexpected results. As of Ansible 1. If mode is not specified and the destination file does not exist, the default umask on the system will be used when setting the mode for the newly created file.
If mode is not specified and the destination file does exist, the mode of the existing file will be used. Specifying mode is the best way to ensure files are created with the correct permissions. See CVE for further details. If a SHA checksum is passed to this parameter, the digest of the destination file will be calculated after it is downloaded to ensure its integrity and verify that the transfer completed successfully.
This option is deprecated and will be removed in version 2. Use option checksum instead. When run on Ansible prior to 2. Influence when to use atomic operation to prevent data corruption or inconsistent reads from the target file.
By default this module uses atomic operations to prevent data corruption or inconsistent reads from the target files, but sometimes systems are configured or just broken in ways that prevent this.

The execute request function is applied to the client object and returns with a response from the server. Once the request is sent to the server we need a response object to receive the data sent from the server. To catch the response from the server we use the HttpResponse class object. The data sent by the server in the form of a message is obtained through the getEntity function.
You can also obtain the response code sent by the server through the response object and use it to your specific need. The data to be downloaded is encapsulated within the entity object and can be extracted using the getContent function. The getContent function returns an InputStream object that can be further used with a BufferedInputStreamReader to enhance performance.
Now all you need to do is read from the stream byte by byte and write the contents into a file using the FileOutputStream class.
The last thing required to be done is closing all the open resources in order to ensure that the system resources are not overutilized and that there are no memory leaks. So there you have it - these are the simplest ways to download a file using the basic Java code and other third party libraries. Now that we are done with the basics, you can be as creative as you want and utilize the knowledge to suit your needs.
